The Company’s reporting units for goodwill are its operating segments, which are also its reportable segments. Since December 31, 2024, management qualitatively assessed whether events during the first six months of 2025 indicated it was more likely than not that the fair value of our reporting units was less than their carrying value, which if the case, could be an indication of a goodwill impairment. Through management’s assessments, no impairment was deemed to have occurred in the continuing segments of the Company. Goodwill in the Natural Gas Distribution and Utility Infrastructure Services segments is included in the respective Condensed Consolidated Balance Sheets as follows: <div style="margin-top:5pt"><table

As such, the Company could no longer assert the ability to complete a tax-free disposition of its investment in Centuri. This event required the Company to recognize a previously unrecorded deferred tax liability related to the outside basis of its investment in Centuri.

Under the terms of the Tax Assets Agreement, it is anticipated that the Company will contribute certain Tax Assets to Centuri, which will be treated as a deemed capital contribution.
